SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 289,344, dated November 27, 1883. Application filed October 12, 1882. (No model.)

To all whom it may concern.-

Be it known that I, JAMES R. GRAY, a citizen of the United States, residing at Ayer, in the county of Middlesex and State of Massachusetts, have invented a new and useful lnr provement in Spindles for Ring Spinning Frames and I do hereby declare the following to be a full, cleaigand exact description thereof, reference being had to the accompanying 1o drawing,which constitutes a part of this specification.

My invention relates to spindles for ringspinning frames, and has for its object to overcome the evil effects due to the tension of the 1 driving-band, and also to enable the spindleto adjust itself laterally upon its lower extremity as a center of motion, as Ihave found that if lateral motion is to be allowed this class of spindles when running, such motion must be from the extreme lower end as a center, otherwise, should the spindle attempt to accoinmodate an unequally-distributed bobbin-load by changing the direction of its axis of rotation, its lower end would be forced to runeccentric, and its upper end would consequently gyrate and describe an orbit with each revo- -lution.

Referring to the accompanying drawing,

which is a sectional elevation of my device,

, 3c my invention will be found to consist, essentially, of a tubular bolster, A, applied to the rail E in the usual manner, and projecting be low the rail, as shown. To the lower end ol the bolster is applied the whirls, adapted to 5 take its lateral support and revolve upon the bolster in a manner similar to a loose pulley upon a shaft, the lower end of the bolster being preferably reduced in external diameter in arder to present asmaller bearing for the 40 whirl. The spindle D is vertically supported by the loose washer to, resting upon the inter nal shoulder of the bolster, and is provided with the long pintle d, which extends down ward through the neck of the bolster and into 4 5 the base ofthe whirl-sleeve,to which it is loosely locked by the pin a, by means of which motion is imparted from the whirl to the spindle, the diameter of the pin being somewhat less than that of the hole through the pintle, and the pintle being so fitted to the base of the whirl thatwhile the upper end of the spindle may sway laterally upon its lower end such lower end shall have no lateral motion, except in common with the whirl 0. The spindle D is laterally supported within the upper end of the bolster by the bushing F, which is loosely fitted within the bolster, and allows the upper end of the spindle to incline laterally in all directions upon its extreme lower end as a center of such motion, such lower end of the spindle having a fixed axis in common with the axis of the whirl c. It will be seen that the entire tension of the driving-band, when applied to the whirl, is exerted against the lower end of the bolster, and the spindle, being 6 loosely supported within the bolster, is free to incline or sway laterally in any direction to a limited extent and change the direction of its axis of rotation at will upon its lower end as a center of such motion, thus enabling the 0 spindle to accommodate itself to an unequallydistributed bobbin-load and to run steadily under such a load. By applying the whirl to the lower end of the bolster, the spindle is not only relieved from the tension of the driving- 7 5 band, but a great simplicity of parts is ob tained, and a consequent saving in cost of construction effected.

Having thus described my invention, what I claim is- 8o 1. The tubular bolster A, having the bushing F loosely fitted within its upper end, the sleevewhirl 0, adapted to rotate upon the lower end of the bolster, and the spindle D, loosely fitting the interior of the bolster and s loosely attached to the base of the whirl-sleeve, substantially as'setforth.

2. The combination, with a spindle and its tubular bolster, of a sleeve-whirl adapted to rotate upon the lower external part of the 0 bolster and loosely locked to the lower end of the spindle, as set forth.
